MAGAZINE LUBRICATOR.

Application filed May 2,

This invention relates to magazine lubricators and has as one of its objects to provide a lubricator that is adaptable to many uses.

Another object of the invention is to provide a lubricator that by its construction is sufiiciently compact to form a practical hub cap for automobiles.

A further object of the invention is to provide a lubricator having a relatively large storage capacity. I

A further object of the invention is to provide a lubricator having an automatic discharge, under pressure, of a predeter mined portion of its contents.

A further obj set of the invention is to provide a lubricator having means whereby an intermittant discharge may be provided, and whereby the discharge may be suspended for an indefinite period.

With these and other objects in view reference is now had to the accompanying drawings in which Fig. 1 is a sectional elevation of the lubricator showing the parts in the position of total discharge;

Fig. 2 is a partial sectional view of the lubricator showing the parts in a position for filling;

Fig. 3 is a partial sectional elevation of a modified form of the luhricator showing its adaptability as a hub cap;

Fig. 4 is a plan view of the head of the magazine;

Fig. 5 is a fragment of the head showing in plan the centrally positioned orifice;

Fig. 6 is an enlarged view of a fragment of the head showing the operation of the latch; and

Fig. 7 is a fragment of the device showing a modified form of studs and head,

Having reference to the drawings like numerals refer to like parts throughout the several views and the numeral 1 refers to the lubricator.

While the application of the lubricator is well understood its application as a hub cap is essentially important and is plainly shown in Fig. 3 where 2 represents a fragment of a hub of an automobile wheel.

The lubricator consists of a cup 3 which from its relatively large capacity, and from the facts that a relatively small portion of its contents is discharged at one time and that the discharge is at optional periods, will be termed a magazine, and as such the 1925. I Serial N0. 27,400.

cup will be referred to in the following pages.

Let it here be understood that the terms automatic and intermittent as herein used will be construed as meaning that the discharge is automatic as it is yieldingly expelled, and that it is intermittent as a portion of its contents is to be discharged at a time and at optional periods.

The magazine 3 is preferably of cylindrical form and its base 4 terminates in a threaded portion 5 for engagement with the parts to be lubricated.

The magazine is provided with an inlet 6 positioned well up on its side wall 7 for a purpose to be explained, and is also provided with the usual discharge orifice 8.

Closing the end of the magazine is a shaped head 9 that is formed with a raised portion 10, shaped as shown in Fig. 1 or with the legs 10 as shown in Fig. 7, for a purpose that will be presently explained, and centrally positioned in the raised portion is an orifice 11 that is preferably shaped as a Greek cross with four equal arms and angles.

A cap 12 is slidably mounted on the magazine in a manner to expose the inlet 6 when the cap is withdrawn its limit, and thus provides an opening through which to fill the magazine, and by the movement of the cap on the magazine to close the inlet during the operation of the lubricator.

The cap is free to rotate on the magazine and has rigidly attached to its central part, on its interior, a regulating stem 13 that is rotatable with the cap, the latter comprising preferably a round rod provided with studs 14 which extend radially from the stem.

The studs are positioned'in staggered relation to each other so as to bring each succeeding pair at right angles to the next pair that they may pass through the centrally positioned orifice 11 in the head 9.

Attached to the regulating stem is a plunger 15 which is constructed of a washer 16, a leather 17, and a second washer 18, all laying adjacent to each other in the usual manner of plunger construction. These three elements are secured to the stem by means of a nut 19 and may be mounted thereon in a manner to enable the stem to be rotated without affecting the plunger.

The plunger is shaped by providing an (ill two

cap it is obviously necessary llpllllllttl. cijlgc bll on the washer 118, as shown in Fig. .l, and the body oi the plum er inn he further shaped (sec hip: 13) by drawing: the edges downward l'roin theplane or the hotly and forming the three elements as one, as and for the purpose ex plaincd below.

Shaping of the plunger is required l'or purposes, i. e. that oi? retaining); a spring 21 in a nei'icrallr central position in the magazine, and to conlorm to the new cral contour oi the hose at when the base is oil pecial desip i'i when the device is used as n huh cap in which case the base is lowcrcdyaway from the diuclnzrpjc orllice to provide for capacity.

Where the luhricator in dot-ii (icd as nhuh to prevent too great an extension of the luhricaler hcnre the hose is lowered as ahore mentioned, and

thus to expel the contents 'troin the lowered base the plunger mnet he shaped to till the :rocess therein.

The spring ill is designed of a conical shape and 1s interposed between the plungver and the head 0 to force the plunger L'Gt-lllll the top 01'' the sprii'ig. Legs l0 may .alsoihe utilized for this purpose if desired.

3y this arrangement the-spring is maintained in its proper position and is thus prevented from moving; laterally against the stem to intercept the studsand thereby intcrlcre with the operation ol' the device.

It is now evident that with the cap 12 withdrawn the plunger will he moved in the sz'une direction asthe cap and ti at this action will uncover the inlet (3 and position the parts so that the inno aiaincnurrhe tilled.

With the filling; arc nnplishcd the spring); which now rom tncsoed, will tend to liorrc urliachargrc oi the tOUiG'llllrL To provide new For controlling; the uction of the plun nrrhy restricting its coinn'essirc movement, and also to provide for a l'reo return movement, a latch 22 is provided which comprises preferably spring members 23 that are secured to the head in nnysuitable manner, as at 24.

The springs are set in the recess 22 to bring: them even with the surface oi the head 9 sothat the head presents a smooth surface on which the studs may he freely turned.

The sprlngs may be curved on one end 25 to supply a seat ttor l'ln' studs l] and are ar ranged with. the curved portion ol each spring resting; opposite to each other and over opposite arms or the cross shaped orilice.

lly this means two oi the studs will he in lcrccpt-ei'l as the stem is moved downward by the action of the spring and to release the studs il lfill'll'lIOSPlTillllQS the cap will. he l'olzitcd one quarter turn which will bring: the intercepted studs l'rce iron'i the springs and in register with the exposed arms ot the orilicc through which they may now pass.

'l heslrin l3 will now move down wnrdaml this niorei'ncnt will continue until. the next succeeding studs are interceptcdhy thelatch.

In withdrawing the on p to renew the charge in the magazine thcstnds will qniss freely through the respective arms .o'lfnthe oril'icc and the latch will perntiitotthis free movement by its yielding qualities, in the ninnne? and as shown in Fig. 6.

It will. thus he acen that the not-ion of the device is intermittent, disol'iargrc taking place only after each quarter rotation of the stem, and. n'adually thereafter, until a certain amount has been discharged depending upon the distance apart ofthestuds.

Thcstuds may also be oblong in section, as, shown in Fig. 7, and positioned-With their long; side vertical thus forming a guide to preventthe rodturning in its upward movement, and in this case the studs will be spaced apart the thicknessio'f the head 9.

In use the device ishttachedto'the journal to he lubricated, the cap is then withdrawn until the orifice is uncovered andthe magazine is thenfilled in thciusnal manner.

The cap is now rotated until the first pair of studs are free of the latch whenthespring 91 will force the plunger against the contents. A specific amountof the lubricant will now be expelled to enter the bearing, and as the lubricant inithe hearingihccomes exhausted the cap will again be rotated a .ipiartentnrn and lubrication .willsbc resumed.

The magazine being); finally emptied the cap lwillhe withdrawn ashcliore, the magazine again lillmhand the operation resumed.
